IMPROVEME NT IN RIBBON-BLOCKS.

Specification forming part of Letters Patent N 0. 199,641, dated January29, 1878 application filed July 18, 1877.

To all whom it may concern:

Be it known that I, THOMAS HAGERTY, of Brooklyn, E. D., in the county ofKings and State of New York, have invented certain new and usefulImprovements in Ribbon-Blocks; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, which willenable others skilled in the art to which it appertains to make and usethe same, referencebeing had to the accompanying drawings, and toletters of reference marked there on, which form a part of thisspecification.

This invention relates to the material used in and construction ofribbon blocks; and consists in the employment of veneers or thin sheetsof wood for the cylinder or tube, the ends to be of wood, either of onethickness or of veneers having the grain thereof crossing each othertransversely, as will be more fully hereinafter described.

In the drawing, Figure 1 is a longitudinal section on line as w of Fig.2, and Fig. 2 a transverse section.

A represents the veneer or thin sheet of Wood which forms the tube, thesquare edges of which meet at a, and form a joint which is to be unitedby glue or cement, and to strengthen which I sometimes employ asplicing-piece, a,

of the same or suitable material, and glue or cement it to the tube oneither side, as seen at a a, Fig. 2. v

The end pieces B B can be made of any desirable thickness, of one pieceof Wood, B, or

of two pieces of veneer, B, glued or cemented together, and having thegrain of one piece transverse to the grain of the other, which willprevent the warping of the ends.-

The veneer A is usually cut from a round log in continuous sheets, whichpreserve the curvature of the same; and hence, in making longribbon-blocks, the veneer is used with the grain of the wood runningparallel with the axis of the block; but I do not confine myself to thisfeature, as it may be suitable to make these blocks with the curvaturein the direction of the grain.

In ribbon-blocks made in this manner, and of veneer or thin sheets ofwood, there is no tendency of the end pieces to drop out after the blockhas been formed, as the seasoning ployed to obviate this difficultywithout entire success, as in mine.

In practice it is found that my method and material employed will reducethe cost of these blocks very considerably.

I claim I Aribbon-block the cylinder or drum of which is made of a thinsheet or veneer of wood, sub stantially as and for the purposedescribed.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.

THOMAS HAGERTY.
